TArray and TSet have supported multiline config values for a long time now, but TMaps have been left out! Here’s a change that addresses that by adding support to LoadConfig/SaveConfig for multiline TMap values in ini files:

Hello Ron.
The timing here is terribly unfortunate. LoadConfig() was edit significantly on Main in 48965206 and the first half of your pull request collides rather heavily as a result. If you can redo the change on Main then we would be happy to reconsider.

It looks like a pretty trivial change (the blocks for each container type were just moved into separate functions), so it shouldn’t be difficult to update. I’ll post an updated change as soon as I can.
